About Silicon Boride SiB6 Powder:
Silicon boride (Silicon Hexaboride) is a shiny black-gray powder with a relative density of 3.0g/cm3 and a melting point of 2200°C. Silicon boride is a lightweight ceramic compound formed between silicon and boron. It is insoluble in water, resistant to oxidation, thermal shock, and chemical attack, especially with high strength and stability under thermal shock. The grinding efficiency is higher than that of boron carbide.
The SiB6 crystal structure includes interconnected icosahedrons (polyhedrons with 20 faces), icosahedral hexahedrons (polyhedrons with 26 faces), and isolated silicon and boron atoms. Compared to hexaboride, it is metastable. However, since crystal nucleation and growth are relatively easy, they can be prepared.
When heated in air or oxygen, the surface of SiB6 is oxidized, and it is attacked by boiling sulfuric acid and fluorine, chlorine and bromine at high temperatures. Silicon boride is conductive. The hexaboride has a low thermal expansion coefficient and a large nuclear cross-section for thermal neutrons.

Feature of Silicon Boride SiB6 Powder:
1. Nano-silicon boride has high purity, small particle size distribution, high specific surface area.
2. The melting point up to 2230 °C. It can not be soluble in water and anti–oxidation and high resistance to chemical attack. especially in the high thermal impact and stability;
3. Grinding efficiency of silicon boride is higher than that of boron carbide, it can be used as abrasives, grinding and engineering ceramics such as nozzles, gas turbine blades and other different sintering conditions and sealing line
How is Silicon Boride SiB6 Powder produced?
A kind of step of preparing silicon boride powder is as follows:
Silicon powder with an average particle size of less than 1 micron and boron powder with an average particle size of fewer than 20 microns are mixed uniformly by a ceramic ball milling tank; the weight ratio of silicon powder and boron powder is 2.85-2.95:7.
After loading the crucible, put it into the gas protection furnace, pass in argon gas, and heat up to 1400-160 (TC, hold for 50-70 minutes;
At the beginning of heat preservation, put ASiCl4 into the furnace, 3-5ml per minute, dripping time 9-11 minutes;
After cooling, the final SiB6 powder product is obtained by crushing with a ceramic pot ball mill.
Application of Silicon Boride SiB6 Powder:
Main uses of silicon boride SiB6 Powder:
1. Used as various standard abrasives and grinding cemented carbides;
2. Used as engineering ceramic materials, as various standard abrasives, and grinding cemented carbide.
3. It is also used as engineering ceramic materials, sandblasting nozzles, and manufacturing blades of gas engines and other special-shaped sintered parts and seals.
4. Used as an anti-oxidant for refractory materials.
Storage Condition of Silicon Boride SiB6 Powder:
The damp reunion will affect SiB6 powder dispersion performance and using effects, therefore, silicon boride SiB6 powder should be sealed in vacuum packing and stored in cool and dry room, the silicon boride SiB6 powder can not be exposure to air. In addition, the SiB6 powder should be avoided under stress.
Packing & Shipping of Silicon Boride SiB6 Powder:
We have many different kinds of packing which depend on the silicon boride SiB6 powder quantity.

Silicon Boride Health & Safety Information
The United States urges the U.N. Security Council to impose additional sanctions on North Korea in response to its latest ballistic missile launch, including a ban on tobacco and oil exports to North Korea and a blacklist of the Lazarus hacking group.
The United States circulated the draft to the 15 members of the Security Council this week. It was not immediately clear if or when a vote would take place. A resolution requires nine "yes" votes and no vetoes from Russia, China, France, Britain, or the United States.
Russia and China have already voiced opposition to tightening sanctions in response to Pyongyang's launch of an intercontinental ballistic missile last month -- the first since 2017.
U.S. and South Korean officials and analysts also say there are growing indications that North Korea may soon conduct its first nuclear weapons test since 2017, too.
The U.S. -drafted U.N. resolution would expand the ban on ballistic missile launches to include cruise missiles or "any other delivery system capable of delivering a nuclear weapon."
The deal would halve crude oil exports to North Korea to 2 million barrels a year and refined oil exports to 250,000 barrels a year. The resolution also seeks to ban North Korea's export of "fossil fuels, mineral oils, and their distilled Silicon Boride are estimated to be influenced by international political situation changes.
